Quality of products

The vast majority of Norinco’s products are intended for use in a field covered by European standard EN 124. Some of the quality marks Norinco works with to certify the products to EN 124 standard are NF, BSI, KOMO, BENOR COPRO and AENOR.

Our construction castings are manufactured using ductile iron. Ductile iron combines the advantages of gray iron with greater strength, toughness, higher impact resistance and increased durability, without additional weight. Because it has the ability to withstand greater loads without failure, it is often specified for extra-heavy load applications.
